I had a clean, fresh install of WordPress since I wanted to start blogging again sometime soon. I noticed that, even with the default themes that I was given with the fresh install, when I clicked the "Preview" button, the theme did not show up and instead showed the current theme my blog is on.
I have no extra plugins except the ones WordPress came with. I have three extra themes and the problem still persists.
Any clue as to why and how to fix this issue?
